I'm gunna throw a wrench into the discussion and go a very different direction.
Why, if production is not a limiting factor are customers having to wait several weeks for custom orders? The capacity is there, so what is the problem? There are 6 colors, so even if the paint area does one color a week, presumably you can rotate through all the colors in 1.5 months. I understand that some colors are more popular, so that might skew a potential custom order if you fall on the wrong end of the production calendar. But I've definitely seen a few post of people waiting 8+ weeks.
Q3 produced 1800 Airs. That comes out to 20 a day? In a factory that can produce 30,000 per year so 80 units per day. That means production is operating at 1/4 capacity.
Is it a BOM problem? This I highly doubt. On more than one occasion they've discussed how small changes in parts, exceedingly simple changes, produces massive changes in the end result. The engineers have done a phenomenal job here. I feel like BOMs are very similar between Air variants and they've done a excellent job around managing this
Is it an employment problem? They have the ability to ramp but perhaps they'd finish production too quickly and employees would be left with idle hands. They can't hire and fire at whim, so instead then intentionally slow production to make work more consistent and even.
I know MRP can be very very complicated but the lingering question for me is if you have a customer who is willing to pay, what is the hold up? It was shocking to see so many 23/34 Airs riddle across the parking lots around the factory, but they've all been sold or leased. Now that this buffer is gone are 2025 customers going have to sit around and wait for their orders? Will this happen with Gravity too? Is this MRP puzzle the reason why Gravity Touring is slated for a later production date?
It's easy enough to say take the money and get the car in their hands. But of course there must be some underlying complex issue and while many people seem to think the product is half baked, not ready or otherwise... I think this is some type form of a production puzzle which is manifesting itself in what we see with delayed custom orders or Gravity GT launching first vs Gravity GT/T simultaneously.
Anyone out there with significant MRP experience who can chime in and add some light on whether or not this might be an issue?
Just a random Sunday morning sitting on the couch thought.
